[Iatrogenic foreign bodies within the maxillofacial region].

Five hundred different X-ray pictures of the maxillofacial region were analysed. Foreign bodies such as dental filling materials and instruments were found. It was stated that most often the excess of endodontic material was observed in the region of a treated tooth. The second site where iatrogenic foreign bodies were found was the maxillary sinus. The reason of these complications was the lack of proper radiological and endometric diagnosis before the beginning of the endodontic treatment.
